In July 2023, the Uxbridge by-election was – rightly or wrongly – interpreted as indicating there was appetite among voters for anti net-zero sentiment and rhetoric. Whilst some of the measures Rishi Sunak subsequently announced in September 2023 – slowing down the phase out of gas boilers and petrol/diesel vehicles – received a positive reaction from Conservative voters in polling, there was no obvious gain in political capital.
The heavy losses incurred by the Conservatives in two subsequent October 2023 by-elections are being read by some political commentators as a sign that the anti net zero push didn’t bring voters flocking back to the party.
Sam Hall, the Director of the Conservative Environment Network (CEN), argued that Sunak is ‘gambling with his party’s hard won green credentials’.
Read the Climate Barometer’s analysis of what the Tamworth and Mid Bedfordshire by-elections do – and don’t – tell us about public opinion on climate policies.
Climate Barometer tracker polling from October 2025 shows that the public primarily hold ‘businesses that pollute the most’, ‘the fossil fuel industry’, and ‘energy companies’ responsible for covering the majority of costs of transitioning to net zero.
This is consistent for almost every voter group, with the exception of Reform UK supporters, who are reluctant to single out the fossil fuel industry, and are more likely to say ‘nothing would make net zero fair (22%), and Green party supporters, who are more likely to hold the wealthiest 1% of households responsible.
Notably, the public do not hold airline companies, the motor vehicle industry, or households who pollute the most – to the same degree of responsibility.
